タの全てが折り返される。As shown in Fig. 2, the conventional control signal transfer method using the control path of time division multiplexing equipment includes an external console 1 that centrally manages and controls a group of time division multiplexing equipment forming a network, and a communication system that performs communication control. Control units 21 and 22, a drop unit 34 that inputs and outputs control signals to and from the control path, an insert unit 31, and a loopback unit 5 that performs a data loopback test.
, an interface unit 4 that converts into a transmission line interface
1 and 42. When performing transmission path return control using an external console l that centrally manages and controls a group of time-division multiplexing devices forming a network, control signals from the external console l are sent via the communication control unit 21 to the insert unit 31. The signal enters the control path assigned to the transmission path and is sent through the interface section 41. Thereafter, it passes through the interface unit 42, extracts only the control signal at the drop unit 34, is processed by the communication control fIIf 322, and performs loopback control to the loopback B5, so that all of the transmission path data is looped back.

た。In this way, in the conventional example, there is no prevention of loopback, so if the transmission line on which control signals are multiplexed is looped back for testing, the control signal sent by the control device may be folded back to the control device. I'll return it. Therefore, communication between the control device and all time division multiplexing devices becomes impossible,
The drawback was that it was not possible to manage and control the time division multiplexing equipment.

タイミングを発生する。The external console 1 performs primary management control of a group of time division multiplexing devices forming a network. When actually controlling a group of time division multiplexing devices, the control signal from the external console 1 is input to the communication control section 2, and the control signal is input to the insert section 3.
A control signal is inserted into the control path assigned to the transmission path from 1, and the transmission path interface conversion is performed by the interface unit 41 and output. In the time division multiplexing device on the receiving side, the interface section 42 converts the transmission line interface, and the drop section 34 extracts the control signal and inputs it to the communication control section 22 . If the control content is a loopback command, it is output to the loopback unit 5 and a loopback test of the transmission path data is executed. The timing generator 6 generates timing corresponding to the position of the control path assigned in the return data.

り返されても制御信号は折り返されない。The control signal insertion section 7 inserts the communication control section 22 at the position of the control path assigned on the transmission path in accordance with this timing.
Insert the control signal from In this way, since the control signal from the communication control unit 22 is inserted at the position of the control path assigned on the transmission path after the loopback unit 5, the control signal is not looped back even if the data is looped back.
